怎么利用JS实现两个select列表对年份、月份进行循环以及默认选中当前年份、当前的月份？请高手指教…

答案：<script type="text/javascript">
window.onload = function()
{
var now = new Date();
var currentYear = now.getFullYear();
var currentMonth = now.getMonth() + 1;
BindSelect(document.getElementById('year'), currentYear - 50, currentYear + 10, currentYear);
BindSelect(document.getElementById('month'), 1, 12, currentMonth);
}

function BindSelect(selectObj, startValue, endValue, selectedValue)
{
var i = 0;
for(var val = startValue; val <= endValue; val++)
{
selectObj.options.add(new Option(val , val));
if(val == selectedValue)selectObj.options[i].selected = true;
i++;
}
}
</script>
<select id="year"></select>年<select id="month"></select>月
